Summary: On 29 April, the LHC team achieved a full machine with 2352 bunches per beam. The beam commissioning and intensity ramp-up were ahead of schedule but faced two challenges: abnormal beam losses in the collimation region on 17 April, leading to a limited squeeze, and a faulty cold compressor on 22 April, temporarily reducing the number of bunches. After repairs, the cooling capacity was restored, and the number of bunches was gradually increased back to 2352 by 29 April. To manage the heat load, the injectors adjusted the bunch pattern. Despite the collimation issue, the machine’s performance and luminosity production are promising for the remainder of the year.
